CM_Register_Notification P/Invoke The callback cannot be captured normally

[yyhLogin]

I want to monitor the USB hot plug event, but the callback is not triggered even though it is registered normally. It is normal in the console program.

internal partial class NativeMethods
{
    internal delegate uint CM_NOTIFY_CALLBACK(IntPtr hNotify, IntPtr context, uint action, IntPtr eventData, uint eventDataSize);

    [LibraryImport("cfgmgr32", EntryPoint = "CM_Register_Notification", SetLastError = true)]
    internal static partial uint CmRegisterNotification(
        IntPtr pFilter,
        IntPtr pContext,
        [MarshalAs(UnmanagedType.FunctionPtr)]CM_NOTIFY_CALLBACK pCallback,
        out IntPtr hNotify
    );

    [LibraryImport("Cfgmgr32", EntryPoint = "CM_Unregister_Notification", SetLastError = true)]
    internal static partial uint CmUnregisterNotification(IntPtr hNotify);
}
